中文摘要:
      辽河油田开发较早,剩余油分布情况十分复杂,储层构型(导致储层内部形成渗流屏障和渗流差异)是造成大量剩余油滞留地下的重要原因。为明确辽河油田Du84块兴隆台Ⅰ段成藏规律及下一步剩余油挖潜方向,综合运用岩心、测井资料对该区进行扇三角洲前缘储层构型研究,分析其储层构型单元特征,为老油田提供剩余油挖潜依据,研究表明:①研究区发育的储层构型单元主要有辫状分流河道,河口坝和分流间湾;②确立了研究区单一砂体的识别标志;③研究区单一砂体垂向叠置模式主要包括垂向叠置、错位叠置及孤立型叠置,单一砂体平面展布样式包括孤立条带状河道、交织条带状及连片状河道。通过对研究区储层构型精细解剖,可以为该区块的开发生产提供重要的指导意义,并为类似区块的扇三角洲储层分析提供借鉴。
英文摘要:
      Liaohe Oilfield developed earlier, and the distribution of remaining oil is very complicated. The reservoir configuration (causing the formation of seepage barrier and seepage difference inside the reservoir) is an important reason for the large amount of remaining oil to remain underground. Through the application of core and logging data, the characteristics of the fan-delta-front reservoir configuration unit are analyzed, and the accumulation law of the XinglongtaiⅠin Block Du-84 of the Liaohe oilfild is determined, which provides a basis for the exploitation of the old oilfield. The research indicates that: ①The reservoir configuration units developed in the study area mainly include braided diversion channel, estuarine dam and diversion bay;②Established the identification mark of a individual sandbody in the study area.;③The identification mark of the individual sandbodies in the study area mainly includes vertical stacking, dislocation stacking and isolated stacking. The individual sandbodies plane spreading pattern includes isolated stripped river,interlaced-stripped channel and large-spread channel. Through the fine anatomy of the reservoir configurations in the study area, it can provide important guiding significance for the development and production of the block, and provide reference for the analysis of fan-delta-reservoirs in similar blocks.
